  • Publication number: 20070212390
    Abstract: The present invention provides modified VEGF-D polypeptide variants that are resistant to serine protease processing and methods of making and using the same, as well pharmaceutical compositions comprising the peptide or a polynucleotide encoding the same. The VEGF-D variants comprise a VEGF homology domain, and at least one of (1) a C-terminal propeptide that is not cleavable by a serine protease, and (2) an N-terminal propeptide that is not cleavable by a serine protease. The VEGF-D variants can be made using site-directed mutagenesis. The VEGF-D variants are useful for the treatment of diseases such as cardiovascular disease and primary and secondary lymphedema, and for the prevention of stenosis and restenosis of blood vessels.

  • Publication number: 20050272664
    Abstract: Proprotein convertase inhibitor has been found to block proteolytic processing and activation of VEGF-C and VEGF-D and inhibit angiogenesis and/or lymphangiogenesis. Method and composition are disclosed for inhibiting angiogenesis and/or lymphangiogenesis, and for treating conditions associated with excessive angiogenesis, such as tumors and/or retinopathies, as well as conditions associated with lymphangiogenesis, such as the metastatic spread of malignancies, macular degeneration, inflammatory mediated diseases, rheumatoid arthritis, diabetic retinopathy and psoriasis in a patient. The inventive method and composition utilize proprotein convertase antagonist selected from the group consisting of an anti-proprotein convertase antibody, an antisense nucleic acid molecule against a polynucleotide coding for a proprotein convertase, and an siRNA for inhibiting proprotein convertase expression, as well as proprotein convertase inhibitors.

  • Publication number: 20050202015
    Abstract: A method for treating and alleviating disease characterized by the expression of VEGF-D involving screening to find an organism with tumor cells expressing VEGF-D and administering an effective amount of a VEGF-D antagonist; a method for screening for neoplastic diseas, where detection of VEGF-D on or in a sample such as tumor cells, blood vessel endothelial cells or lymph vessel endothelial cells indicates neoplastic disease; a method for promoting and maintaining vascularization of normal tissue in an organism involving administering a vascularization promoting amount of VEGF-D or a fragment or analog thereof to the organism; a method for screening tumors for metastatic risk involving detecting expression of VEFG-D by a tumor which indicates metastatic risk; and a method of detecting micro-metastasis of neoplastic disease involving detection of VEGF-D on or in a tissue sample which indicates metastasis of a neoplastic disease.

  • Publication number: 20040115660
    Abstract: The present invention relates generally to a method for detecting abnormalities or a propensity for an abnormality to occur in an animal such as a human. The abnormality of the present invention relates generally to conditions arising from interruption in signalling associated with receptor-type tyrosine kinase-like molecules and in particular RYK (related to tyrosine kinase) receptors. Such abnormalities include aberrations in the normal morphogenesis of craniofacial structures including secondary palate as well as a range of aberrations resulting in neural conditions affecting angiogenesis and conditions affecting muscle development or maintenance. The present invention permits the early diagnosis of such defects and conditions such as in utero and provides a means for genetic or other therapeutic intervention.
